Clinically,
occlusion of the central retinal vein is manifest by a painless decrease
in vision which is usually not as severe as that seen in arterial
occlusion.Fundus examination
reveals wide-spread hemorrhages throughout the retina with swelling and
edema(#22030).The degree of
retinal involvement depends on whether the venous occlusion is a partial
or incomplete occlusion (venous stasis retinopathy--non-ischemic) or a
more complete central retinal vein occlusion (hemorrhagic retinopathy--
ischemic).Gross
histopathologic examination reveals wide-spread hemorrhages throughout the
entire retina(#22031).Histopathologic
examination reveals hemorrhages throughout all layers of the retina with
diffuse areas of hemorrhagic infarct and ischemia(#22033).
